How To Build A Wooden Stand Up Paddle Board

In this article, we will show you how to build a wooden stand-up paddle board. SUP boards are becoming more and more popular, and for good reason – they are a lot of fun! 

Not only that, but they are also great exercise. In order to build your own SUP board, you will need some basic carpentry skills and tools. 

We will walk you through the entire process step-by-step, so don’t worry if you’re not familiar with carpentry terminology.

Choose The Right Type Of Wood

The first step is to choose the right type of wood for your SUP board. The two most common types of wood used for SUP boards are plywood and cedar. 

Plywood is the more popular choice because it is cheaper and easier to work with. However, cedar is a good choice if you want your board to be lighter and more durable.

You will also need to decide how many layers of wood you want your board to have. Most SUP boards have three or four layers of wood. 

We recommend using four layers of plywood for your first board. This will make it strong enough without making it too heavy.

How To Select The Right Wood

The next step is to select the right wood for your SUP board. You will need to find a piece of plywood that is at least eight feet long and four feet wide. 

The thickness of the plywood will depend on how many layers you are using. If you are using four layers, then you will need three-quarter-inch thick plywood.

You can buy plywood from your local hardware store or online. We recommend buying from a local store so that you can inspect the wood before you buy it.

When choosing plywood, look for sheets that are free of knots and voids. These defects can weaken the structure of your SUP board.

Finally, make sure to ask for marine-grade plywood. This type of plywood is designed to withstand the harsh conditions of the ocean.

Cut The Wood To The Correct Size

Now that you have your plywood, you need to cut it to the correct size. The first step is to mark out the dimensions of your board on the plywood. 

We recommend making your SUP board nine feet long and three feet wide.

Once you have marked out the dimensions, use a saw to cut the plywood along the lines. If you don’t have a saw, you can ask someone at the hardware store to cut the wood for you.

After cutting the plywood, sand down all of the edges with a sander. This will make sure that there are no sharp edges on your board.

Drill Holes For The Screws And Bolts

The next step is to drill holes for the screws and bolts. You will need to drill eight holes in total – four on each side of the board.

Start by drilling a pilot hole in the center of each side of the board. Then, use a spade bit to enlarge the holes so that they are big enough for the screws and bolts.

Finally, countersink the holes so that the heads of the screws and bolts will be flush with the surface of the plywood.

Assemble The Stand Up Paddle Board Frame

Now it’s time to assemble the frame of your SUP board. Start by attaching the two side rails to the top and bottom plates with screws and bolts.

Make sure that the frame is square before you move on to the next step.

Once the frame is square, attach the cross braces to the side rails. The cross braces will help to reinforce the structure of your SUP board.

Finally, attach the deck plate to the top of the frame. This will be the surface that you stand on when you are paddling your board.

You can now remove any clamps or jigs that you used to hold the pieces of wood in place while you were assembling them.

Install The Decking And Rails

Now it’s time to install the decking and rails on your SUP board. Start by installing the front and back rails. 

The rails will help to keep your feet in place while you are paddling.

Then, install the decking. Make sure that the edges of the decking are flush with the edge of the rails.

If you want, you can also install a nose guard to protect the front of your board from damage.

The final step is to attach a fin box to the bottom of your board. This will allow you to attach a fin to your SUP board.

Sand And Finish The Stand-Up Paddle Board

The last step is to sand and finishes your SUP board. Start by sanding down all of the surfaces with 120-grit sandpaper. 

This will help to remove any rough edges or splinters.

Then, apply a coat of wood sealer to all of the surfaces. This will protect your board from water and UV damage.

Finally, apply a coat of paint or varnish to the decking and rails. We recommend using marine-grade paint or varnish for extra protection.

Cons And Pros Of Building A Wooden Stand Up Paddle Board

There are a few cons and pros to building your own wooden SUP board.

The biggest con is the amount of time and effort that it takes to build aboard. It can take several days or even weeks to build a board from scratch.

However, the end result is worth all the effort. You will have a custom-made stand-up paddle board that is perfect for your needs.

The other downside is the cost. Building your own SUP board can be expensive, especially if you buy all of the materials from a hardware store.

But, if you already have some of the materials lying around, then the cost isn’t too bad.


Building your own wooden SUP board is a great way to get a custom-made board that is perfect for your needs. It can be time-consuming and expensive, but the end result is worth it.
